A paper published last year in Icarus, the prestigious journal of planetary science, asked if it was possible that terrestrial life on Earth had been ‘seeded’ from beyond the Earth – and if so, does the building block of that life, DNA, contain any sort of message from our alien creators. Using mathematics, the authors of the paper – “The “Wow! signal” of the terrestrial genetic code” – looked for evidence of a statistically strong ‘informational’ signal in the genetic code, with surprising results.

The DNA data, according to the paper, display readily recognizable hallmarks of artificiality.

This was not the first time that Icarus had featured a paper entertaining the idea of ‘biological SETI’. In 1979 the journal – under editor Carl Sagan – published a paper titled “Is bacteriophage φX174 DNA a message from an extraterrestrial intelligence?”, written by Japanese biochemists Hiromitsu Yokoo and Tairo Oshima. Given how crazy the idea sounded, Sagan asked a young protégé, David Grinspoon (now a prominent astrobiologist in his own right), to check out the paper to assess whether it was legitimate. (1)

Despite of the outcome – which will need of course more research to validate – what is important is that science can only progress if it analyzes the obvious. Question what is right in front of your, ask about things taken for granted and you shall see miracles. There is no such thing as “junk” (junk DNA). Even the trashiest garbage bin can contain gold…

3D printing as a way to skills oblivion, monuments, aliens.

3D printers now print even metal and are getting bigger and better. (1, 2)

The old craft of metal manufacturing and welding will soon be forgotten.

Oh, I would love to see the faces of “high tech” people of the future when for some reason their machines break or when they will just want to create something not created by these machines… 🙂

We often wander how we are so incapable of doing things the ancient people did – like moving giant stones to create giant monuments. We have lost that skill due to technology. We have become too lazy to even be willing to learn that skill. And not we believe all ancient monuments were built by alines. How… human!

We once knew how to do everything! Too much “knowledge” had made us dumb…
